Electrochemical breathalyzer The DA 8500 E breathalyzer is a product valued by professionals who expect the highest quality and strict requirements. Measurement reliability, accuracy, durability - find out why AlcoFind personal breathalysers are among the most frequently purchased sobriety testers. Accuracy of the electrochemical sensor Accurate electrochemical sensor , representative of the highest quality in personal breathalyzer sensors. It is characterized by exceptional precision and repeatability of measurements . Because it only responds to alcohol , other factors (including battery discharge) do not affect the test. The electrochemical sensor is a guarantee of reliability . Main features: memory of the last 50 results counter of performed tests 4-digit backlit LED display automatic power cut off function battery level indicator low battery indication sound signaling readiness for measurement sound signaling of the beginning or end of the measurement possibility to change measurement units ( percent BAC, g or l, mg or l, ‰) Guaranteed measurement reliability Precision is one of the most important features of a well-conducted study. The result given with an accuracy to hundredths will allow you to clearly determine whether you can safely sit behind the wheel. In combination with a wide measuring range of up to five per mille, it gives a package that allows you to be sure of the result. A practical case is included The breathalyzer comes with an original cover that protects the device from scratches. Thanks to the practical case, the tester is resistant to mechanical damage, and you can enjoy high quality measurements for longer Kit Contents: breathalyzer DA-8500E practical velcro pouch batteries type AAA: 2 pcs.
